Technically it's a solid 7.5 but I feel no regret in putting this on 8 since it's incredibly good for such a short-kinda of manga but it has some things that I understand and would've liked much more if it was fleshed out. But even as it is, I loved reading it! It has a nice pace without feeling terribly rushed and there were a lot of surprises along the way that I liked seeing. "Precious life lessons" is also a nice way to put into it. Nanami is such a lovely protagonist and I loved all the three boys (and know why it wouldbe so difficult for readers to choose between "the actual perfect ML"). I like Ichijou a lot tho, but maybe it's because I'm okay with his type of awkward yet kind character. Chihiro is best boy™, deserves the world, and Ieiri surprised me a lot... they all need to be happy, that's my final thought.
